Just a short note for people who are delighted to shoot themselves in the foot, like me, and waste a few hours trying to stop the resulting blood fountain: gap4 need "libg2c", a special Fortran/C library. With previous versions of (K)Ubuntu, that could simply be installed via apt-get (apt-get install libg2c0), but 9.10 does not have this package anymore (or at the moment). Resolution: 1) from an earlier distribution (9.04 is just fine), copy /usr/lib/libg2c.so.0.0.0 to /usr/lib of your new distribution 2) set a link from libg2c.so.0 to libg2c.so.0.0.0 3) install libstdc++.so.5 gap4 then runs fine again *phew* Bastien PS: if you don't HAVE an earlier installation, or, like me, the upgrade from 9.04 to 9.10 deleted the files: use virtualbox to install a 9.04 with libg2c, then copy over the files from the virtual machine to your real installation.
